One fifth urinate in public pool
|
|
|
According to a survey of about 1000 people in the USA, one fifth admitted they urinate in public pools. However, because the chlorine levels of the water in public swimming pools are not high enough, the urine in the water does do harm to the swimmers. So, next time, when you jump into a swimming pool, please consider other choices.  |
